Built to minimize interference with your natural stride, the Brooks PureCadence 6 frees your feet to run faster and farther. A 3D fit print upper provides a seamless feel that hugs your foot. Advanced BioMoGo DNA midsole cushioning adapts to each step to support whole body alignment. With an innovative guide rail system and external heel clip, these shoes allow your hips, knees and joints to find your natural motion pattern. The lightweight PureCadence 6 features omega flex grooves to enhance midsole flexibility for a smooth forefoot ride. A slight curve in the rounded heel shifts the point of force forward to align through the center of the ankle. Enjoy the comfort of a plush collar and an articulated sockliner.
